Lots of security, parking lot wasn't a mess. That's a great start to the night.
Then it happened... Once we exited the venue I knew we were in trouble. The parking lot was exactly that a parking lot. I seriously waited 1 hour in the parking lot. Every few minutes i would move a few feet. I don't want to give the Mandalay Bay a bad review because of the parking garage, but this was seriously the worse. WE planned on getting some grub after the concert, but the parking lot situation sucked the life out of me. I was drained...in fact it was so bad that people started to argue with one another outside of their vehicles. (trust me it was comical, because it didn't solve anything at all. )
The rest of the Mandalay Bay is amazing. Just don't park in the parking garage during a concert.
